Orford, Suffolk [Coralline Crag] (Pliocene of the United Kingdom)

Where: England, United Kingdom (52.1° N, 1.5° E: paleocoordinates 52.2° N, 1.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Coralline Crag Formation, Zanclean (5.3 - 3.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Coralline Crag, which is regionally overlain by the Red Crag. AGE: It has been correlated with, but probably predates at 4.4 to 3.8 Ma, the Luchtbal Sand Member of the Lillo Formation in the Antwerp area on the basis of molluscs (Cambridge, 1977), foraminifera (Jenkins and Houghton, 1987) and dinoflagellate cysts (Louwye et al., 2004; De Schepper et al., 2009), placing it in the latter part of the early Pliocene (Zanclean 2) of the southern North Sea. STRATIGRAPHIC POSITION: From unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified siliciclastic sediments

• ENVIRONMENT: Shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Not stated in text, but siliciclastic based on observation of specimens. LITHIFICATION: Unlithified, based on observation and figured specimens.

Size class: macrofossils

Preservation: original aragonite, original calcite

Collection methods: COLLECTOR: Not stated, but probably Stearns Wood, c. 1840's-1870's. REPOSITORY: Not stated in text.
